Green industry work: production of FeCl from iron and steel industry waste (mill scale) and its use in wastewater treatment.

Mill scale (MS) is considered to be a significant metallurgical waste, but there is no economical method yet to utilize its metal content. In this study, which covers various processes in several stages, the solution of iron in MS, which is the Iron and Steel Industry (I&SI) waste, as FeCl (MS-FeCl) in the thermoreactor in the presence of HCl, was investigated. In the next step, the conditions for using this solution as a coagulant in the treatment of I&SI wastewater were investigated using the jar test.

Preparation and characterization of activated carbons from Lemon Pulp for oxytetracycline removal.

This study aims to remove oxytetracycline (OTC) that harms the ecosystem, with activated carbon (LPAC) obtained from Lemon Pulp (LP). Characterization and properties of LPAC were analyzed by Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), X-ray diffraction (XRD) and point of zero charge (pH) analyses. BET surface area, pore volume and pH of LPAC produced by carbonization at 400 °C and activation with KOH at 800 °C were obtained as 1333.
